4. Description

4.1 Mechanical Design

Torque sensors Type 4501A… comprise a rotating shaft

mounted on bearings inside a housing. The shaft has a

necked section - called the torsion zone - to which strain

gages are attached and connected in a full bridge circuit.

Slip rings and brushes provide the link between rotor and

housing with two slip rings carrying the electric power

supply to the strain gages on the rotating shaft. Two other

slip rings serve to transfer the measuring signals from the

rotating shaft to the stationary housing. The full bridge

circuit is connected directly through the slip rings and

brushes to the lead connector which is mounted on the

housing of the torque sensor.

In version QA torque sensors an optical rotation angle

measurement system is integrated. It consists of a pulse

disk on the rotating shaft with 360 light-dark stripes. Two

light barriers are installed into the stator. Inside the torque

sensor there is a small electronics for processing of the

angle pulses.

5.2 Installing the Signal Lead

 Do not run the lead parallel to power cables or control

circuits.

 Do not place the lead close to equipment producing

strong electromagnetic fields, e.g. transformers, wel-

ders, contactors, electric motors, etc.

 If such situations cannot be avoided, run the lead inside

earthed steel conduit.

 Excess lengths should be prevented. If it isn’t possible to

avoid, then do not lay excess lengths in closed loops.

Fig. 12: Laying of the measuring cable

Risk to couple in EMC noises into the

measuring sensor cable

To reduce the inductive areas it’s

recommended to laying the measuring

7. Static Calibration

This

rocedure re

uires the use of a calibration device

with a lever arm and weights for producing specific

values of torque.

The calibration procedure is as follows

 Apply the rated value of torque to the torque sensor

and then remove it again

 Adjust the zero reading accurately

 Apply a known value of torque to the torque sensor.

 Adjust the displayed reading to the corresponding value

Plotting a calibration curve

 Calibrate the torque sensor as described above.

 Apply torque in 1/10 steps up to the full rated value

and then remove it again in the same way.

A delay of at least 30 seconds must be allowed

between the individual 1/10 steps so that each reading

can stabilize before it is recorded
